IBM PC 5150 with no drives?

The original IBM PC (5150) had 16K of memory (NOT 4k - THAT was the TRS-80 :-), expandable by populating sockets to 64K. Case, power supply, motherboard with "Cassette BASIC" in ROM, and keyboard. It sold for about $1320. Without video, without disk controller, without drives, without serial, without parallel. It wasn't usable without adding video. Although I did know one person who hooked up a votrax, and never used her video other than to have a friend load software in from cassette to "boot". There was a built in cassette interface. IBM never sold the cable for it, but the pinout matched the TRS-80, so the RS 26-???? cable worked. Most people opted for "complete systems", which added $400 @ for Tandon TM100-1 single sided full height drives, ~$300 for disk controller, ~$300 for video card, ~$600 for monitor, and a few hundred dollars for each row of 16K memory. In addition to portability, that meant that Compaq could claim to provide enormous cost savings, by selling their machine for "LESS THAN $3000". But among those rare few of the populace who understood how to use a screwdriver, the cheapest route to a PC was the $1320 base machine, plus disk controller, and CGA video card. Then go aftermarket (mostly TRS-80 suppliers) for drives at less than $200 @, cheap memory, and a composite "closed circuit TV" monitor. Within another year or two, aftermarket accessory boards became available, and eventually clones and clone motherboards. IBM's braindead decision to have 5 (instead of 8) expansion slots meant that aftermarket "multifunction" cards became quite popular. MANY of them advertised SIX functions; after memory, serial, parallel, and joystick, how many people remember what purported to be the other two functions? But the original $1320 5150 was devoid of drives and cards. ** FS (after I back off all of the mods and put the original pieces back in) ** -- Fred Cisin cisin(a)xenosoft.com XenoSoft http://www.xenosoft.com 2210 Sixth St. (510) 644-9366 Berkeley, CA 94710-2219
